Any advice on aphids?

Hi.

Aphids are starting to discover my tomato plants. There aren't many yet (about 15-20 at most on one plant, less on others). Do I need to do something about them right away or is there not much yet to worry about? I realise it might be a daft question but this is the first year I've ever actually tried to grow anything so I'm on a steep learning curve!

If anyone has any advice on what I should do I would be very grateful. I've got some greenhouse flypaper traps from B&Q but as yet the aphids have practically ignored them. The aphids themselves seem to be greenfly, whitefly and small black flies too.

Thanks.:D

 

Your only hope is to spray with an insecticide, to get the blighters before they start breeding, especially the Whitefly.

I have tried every thing, yellow strips, plain water spray, smoke bombs and insecticide sprays, and the Whitefly still win!

I think the soapy water could be the better bet although of the three sugestions a good insecticide will sort the ******s.

 

If you have white fly then make the atmosphere a little damper by spraying the floor etc. They thrive when climate is hot and dry. Greenfly just thrive!

Nothing to stop you gently crushing the aphid cluster with finger and thumb using enough pressure to kill but not damage the stems of the plant. Look in the centres of the stems and rub out the aphids.

Some people grow marigolds in pots between the plants. marigolds are supposed to attract the aphids natural predaters.

Last resort chemical spray like Derris or a soap solution. Spray at night or the leaves might scortch and end up with white blotches.

Keep at it!
